EASTHAMPTON - After three years of work that backed up traffic on Interstate 91 and often created headaches for motorists, the state Department of Transportation is putting the finishing touches on a bridge project that crosses East Street.

According to Rich Nangle, a spokesman for the department, all that’s left to be done is the repaving of East Street below the bridge and the seeding of the highway embankment.

That work is scheduled to be done this week and will necessitate alternating one-way traffic on East Street during the day, Nangle said.
